So, what does Andrew Clutterbuck think about Jethro Tull music ?

I saw him on Letterman I think and it seemed like he thought his famous father-in-law was kind of crazy - he, the father-in-law had a whole room full of guns and weapons and such. I wonder if he has ever let it slip whether he is a fan or hates Jethro Tull music. Maybe his wife would not like it so he has to not like it as well? Any news on this?
